Apart from Meta-data is there a provision to define some name-value pairs in the jboss-aop.xml file that could be rendered by the interceptors or advice classes ? It was'nt obvious to me from the documentation. Any possibility of adding that feature ?

I haven't documented it yet, but if the Interceptor class implements org.jboss.util.xml.XmlLoadable then the importXml will be called at interceptor creation time. I will eventually add this to the creation of aspects as well.
